The California Air Resources Board (CARB) is proposing a law (part of the state Green House Gas Initiative) to stop the sale of refrigrants (134a) to consumers. Note the article below that states "What costs consumer $10 today for a can of auto refrigerant will cost them $150 or more tomorrow if CARB gets their way". Wonder what R12 will cost then. Maybe I should stock up now!
